How To Fix Dummy Audio on Laptop After Updating to Ubuntu 22.10

Ubuntu 16

In this article, we will explore various ways to fix the “Dummy Audio” issue on a laptop after updating to Ubuntu 22.10. This problem typically arises when Ubuntu fails to recognize the sound card after an update.

Quick Answer

To fix the "Dummy Audio" issue on a laptop after updating to Ubuntu 22.10, you can try enabling and starting PulseAudio, restarting Pipewire and reinstalling the Pipewire Media Session, or booting into the latest kernel version. If none of these solutions work, it may be necessary to seek further assistance or consult with a professional.

Understanding the Problem

After updating from Ubuntu 22.04 to 22.10, you may find that your laptop only shows “Dummy Audio” and does not recognize the sound card. This can be frustrating, especially if you rely on audio for tasks like video conferencing, listening to music, or watching videos.

Solution 1: Enable and Start PulseAudio

PulseAudio is a sound system for POSIX OSes, meaning it is a proxy for your sound applications. It allows you to do advanced operations on your sound data as it passes between your application and your hardware. Things like transferring the audio to a different machine, changing the sample format or channel count, and mixing several sounds into one are easily achieved using PulseAudio.

You can enable and start PulseAudio by entering the following commands in the terminal:

systemctl --user enable pulseaudio
systemctl --user start pulseaudio

The systemctl command is used to examine and control the state of the “systemd” system and service manager. In this case, we are using it to enable and start PulseAudio.

Solution 2: Restart Pipewire and Reinstall Pipewire Media Session

Pipewire is a server or daemon that provides multimedia handling capabilities, similar to what PulseAudio and Jack do. It’s designed to handle both audio and video streams and can also manage audio on your system.

You can restart Pipewire and reinstall the Pipewire Media Session by entering the following commands in the terminal:

systemctl --user restart pipewire pipewire-pulse
sudo apt --reinstall install pipewire-media-session

The systemctl command here is used to restart the Pipewire and Pipewire Pulse services. The sudo apt --reinstall install command is used to reinstall the Pipewire Media Session.

Solution 3: Boot into the Latest Kernel Version

The kernel is the core of the operating system. It’s responsible for interfacing all of your applications that are running in “user mode†down to the physical hardware, and allowing processes, known as servers, to get information from each other using inter-process communication (IPC).

Some users have reported that booting into the latest kernel version (e.g., 5.15.0-52-generic) has resolved the issue for them.

Additional Help

If none of these solutions work, it may be helpful to check for any relevant updates or patches specific to your sound card or driver. You can also consider seeking further assistance on forums or community websites dedicated to Linux and Ubuntu, such as the Linux.org thread or Ask Ubuntu.

Conclusion

The “Dummy Audio” issue on a laptop after updating to Ubuntu 22.10 can be frustrating, but there are several potential solutions. By enabling and starting PulseAudio, restarting Pipewire and reinstalling the Pipewire Media Session, or booting into the latest kernel version, you may be able to resolve the issue. If not, don’t hesitate to seek further assistance online or consult with a professional. Remember, it’s always recommended to backup important data and consult official documentation or seek professional support if needed.
